Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YS05S10 non- isolated DC-DC converter delivers up to 10 A of output current in an industry-standard surface-mount package. Operating from a 3.0 5.5 V input, the YS05S10 converter is an ideal choice for Intermediate Bus Architectures where Point-of-Load (POL) power delivery is generally a requirement. It provides an extremely tightly-regulated programmable output voltage from 0.7525 V to 3.63 V. The YS05S10 converter provides exceptional thermal performance, even in high temperature environments with RoHS lead-free solder and lead-solder-exempted m products are available without airflow at natural convection. This performance is Delivers up to 10 A (36 W) accomplished through the use of advanced circuitry, packaging, and processing techniques to achieve a design No derating up to 85 C possessing ultra-high efficiency, excellent thermal Surface-mount package management, and a very low-body profile. Industry-standard footprint and pinout The low-body profile and the preclusion of heat sinks Small size and low profile: 1.30 x 0.53 x 0.314 minimize impedance to system airflow, thus enhancing (33.02 x 13.46 x 7.98 mm) cooling for both upstream and downstream devices. The Weight: 0.22 oz 6.12 g use of 100% automation for assembly, coupled with Coplanarity less than 0.003, maximum advanced power electronics and thermal design, results in Synchronous Buck Converter topology a product with extremely high reliability.
